The NCAA Tournament Selection Show earned a 1.6 overnight rating on TBS Sunday, down 52% from last year (3.3), down 57% from 2016 (3.7), and the lowest overnight in the history of the show.

Overnights have now declined in five straight years, though this year’s drop was significantly steeper than usual.

According to Sports Business Daily, overnights peaked at a 2.3 from 6:15-6:30 PM ET, with the first 45 minutes of the two-hour show averaging a 2.2.

On Selection Sunday, the Selection Show ranked just fourth among all sports telecasts behind Tiger Woods‘ near-victory at the PGA Tampa Bay Championship (5.1), NASCAR from Phoenix (2.7) and the NBA on ABC (1.8).

Yikes.

A decent amount of this can probably be attributed to the show moving from CBS to TBS, but the format probably played somewhat of a factor, too.
